Badger Meter 226 Specifications

Badger
Series 200

The Badger Meter Series 200 fl ow sensors feature a six bladed
impeller design with a proprietary non-magnetic sensing
mechanism. The forward swept impeller shape provides higher,
more consistent torque and is less prone to be fouled by water
borne debris. The forward curved shape coupled with the
absence of magnetic drag provides improved operation and
repeatability even at lower fl ow rates. This is especially true
where the impeller is exposed to metallic or rust particles found
in steel or iron pipes. As the liquid fl ow turns the impeller, a low
impedance square wave signal is transmitted with a frequency
proportional to the fl ow rate. The signal can travel up to 2000
feet between the fl ow sensor and the display unit without the
need for amplifi cation. All sensors except irrigation versions are
supplied with 20 feet of 2-conductor 20 A WG shielded U.L. type
PTLC 105°C cable.

MODEL 225BR AND 226BR/226SS SENSORS

The Model 225BR and 226BR/226SS sensors are used for fl ow
measuring applications in most metallic or non-metallic pipes
where it would be diffi cult to shut down or drain the line for
installation or service. The Model 225 features a gate valve for
isolation. The Model 226 uses a ball valve. If the pipe is to be
hot tapped, the ball valve is recommended. The sensor mounts
in a 2” NPT pipe saddle or Threadolet® for installation in pipe
sizes from 3” to over 40”. Positioning nuts on the three threaded
retaining rods allow the sensor to be accurately positioned to
a standard insertion depth of 1½” into the pipe. When this
insertion depth is maintained, and there are at least 10 upstream
and 5 downstream diameters of straight uninterrupted fl ow, an
accuracy of +/-1% of full scale can be obtained between fl ow
velocities of 0.5 to 30 feet/second. Each sensor is equipped
with an isolation valve and pipe nipple to allow the sensor to
be installed in a pressurized pipe. This is accomplished by fi rst
attaching a saddle or Threadolet® to the pipe and screwing the
nipple and isolation valve into the saddle or Threadolet fi tting. A
hole is then drilled through the pipe using a commercial tapping
machine. When completed, the tapping apparatus is removed,
the isolation valve is closed, and the sensor is installed using a
Model HTT Hot Tap Tool.

NOTE: that the overall length of the sensor tube is 18 inches
(457mm), however, a clearance height of 35 inches (127mm)
should be allowed for the fully extended length of the sensor
tube outside the isolation valve.
